Notice of a special meeting shall also state the purpose or purposes for which the meeting is called, and shall indicate that it is being issued by, or at the direction of, the person or persons calling the meeting. If, at any meeting, action is proposed to be taken that would, if taken, entitle shareholders to receive payment for their shares pursuant to Statute, the notice of such meeting shall include a statement of that purpose and to that effect. If mailed, such notice shall be directed to each such shareholder at his address, as it appears on the records of the shareholders of the Corporation, unless he shall have previously filed with the Secretary of the Corporation a written request that notices intended for him be mailed to some other address, in which case, it shall be mailed to the address designated in such request.
